Plaster Drain
RIW Plaster Drain is an internal tanking drainage system comprising internal drainage boards used to collect water entering the basements and sub-structures and channelling it to a sump or collection point for disposal.
RIW Plaster Drain internal drainage boards are a clear high density polyethylene drain board with 5mm undercut studs in a dovetail shape which forms the key for plaster and render finishes used in situations where site conditions or structural design make it difficult or impossible to use traditional tanking methods.
